Investigating Solutions To Wind Washing Issues In 2-Story Florida Homes; Phase 1, Florida Solar Energy Center, Charles Withers, Jr. Dec 2009

Investigating Solutions To Wind Washing Issues In 2-Story Florida Homes; Phase 1, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

Wind washing has been identified as a potentially significant issue regarding energy, demand, comfort, and humidity in some two-story Florida homes. In its most common configuration, wind washing occurs when attic spaces over first-floor portions of the home abut the second story, and the floor cavity of the second story is open to that attic space. Wind blowing into attic vents can push hot attic air into the inter-story floor cavity, bypassing the typical thermal boundaries of the building and introducing considerable heat into the house. Wind washing can also occur when there is little or no attic involved, where …

A December To Remember, Richard C. Crepeau Dec 2009

A December To Remember, Richard C. Crepeau

On Sport and Society

It has been a December to remember. As the month comes to a close with a remarkable flurry of headline sports stories, its clear that this one month was not only one for the memory bank, but that it may have been the most fitting way to end a year that has certified the decade as the Naughty Naughties. What seemed like an awkward tag at the beginning of the new century has become a most appropriate signature phrase as this decade comes to its ignominious close.

Nightcool: Nocturnal Radiation Cooling Concept, Long Term Performance Evaluation, Florida Solar Energy Center, John Sherwin

FSEC Energy Research Center®

An experimental evaluation has been conducted on a building-integrated night sky cooling system designed to substantially reduce space cooling needs in homes in North American climates. The system uses a sealed attic covered by a highly conductive metal roof (a roof integrated radiator) which is selectively linked by air flow to the main zone with the attic zone to provide cooling - largely during nighttime hours. Available house mass is used to store sensible cooling. The system's capability for solar dehumidification with minimal electricity input is demonstrated with long-term performance data taken over 2007 - 2009. A year-long study period …

Multi-Transducer/Antenna Surface Acoustic Wave Device Sensor And Tag (Cip Of 11/203,260), Donald Malocha Nov 2009

Multi-Transducer/Antenna Surface Acoustic Wave Device Sensor And Tag (Cip Of 11/203,260), Donald Malocha

UCF Patents

A surface acoustic wave sensor or tag having multiple transducer/antenna pairs each having a different center frequency. The bandwidth of each transducer/antenna pair is inversely proportional to the number of transducer/antenna used and the bandwidth is the sum of the bandwidth transducer/antenna pairs. Implementing a SAW sensor or tag with multiple transducer/antenna pairs significantly reduces devices losses and improves the performance of the device since the individual transducer/antenna pair's fractional bandwidth is reduced by the ratio of the system bandwidth to the number of transducer/antenna pairs used in the sensor.

Developing G-Rim And Participants Tests For Specific Commercial Programs For The Florida Natural Gas Association, Florida Solar Energy Center, Richard Raustad

FSEC Energy Research Center®

The Florida Solar Energy Center performed an economic assessment for 7 common commercial appliances. This assessment calculates the gas rate impact measure and participants test score for selecting natural gas equipment over comparable electric equipment over a 20-year period. This type of analysis provides an indication whether or not the specific appliance program favors the end use customer and/or the utility company as economic beneficiaries. Given the project assumptions, all natural gas equipment types, with the exception of the pool heat pump water heater, show measures greater than 1 indicating that the natural gas appliance will have lower life-cycle costs …
